#### Circle Basic Scan - Measured Point Method

To generate a circle without the use of CAD data, take three hits in the hole (or on the stud). PC-DMIS calculates the circle using all three hits.

You can take additional hits. PC-DMIS uses the data from all of the measured hits.

- The Centroid that appears in the BASICSCAN dialog box (Insert | Scan | Circle) is the calculated center of the hole (or stud).

- The CutVec is automatically calculated from the plane defined by the three hits.

- The InitVec of the circle is calculated based on the first of the three hits that are used to calculate the circle.

- The Angle is calculated as the angle of the arc from the first hit to the last hit.
